Re: griptape on bokken
I find it a bit odd -- are you needing to grip your bokuto so strongly that you need tape on the handle to keep it in your hands?
I prefer to have a soft yet connected grip on my bokuto myself and find putting tape and such on weapons unneccesary. If someone hits my bokuto to hard it's about to fly out of my hand, I move my body or let go of one of my hands rather than trying to keep a deathgrip on it...
Others may feel differently, though. Just my thoughts.
